ABSTRACT

Objective To investigate the long time prognosis of liver resection or transcatheter arterial chemoembolization(TACE) of Barcelona clinic liver cancer stage C(BCLC-C) patients who have portal vein tumor thrombsis.Methods Totally 86 BCLC-C patients who satisfied our including criteria from our surgical database of People's Hospital of Yichang City from January 2000 to September 2015 were selected as the research object.According to different treatment,86 patients were divided into liver resection group(n=50) and TACE group(n=36).The general information of two groups were compared.Cox multi-factors analysis and overall survival rate were calculated.ResultsThe long-term prognosis of liver resection group was better than that of TACE group(5-year OS:26% vs.0,P40 IU/L(HR:0.615,95%CI[0.488,1.206],P=0.013) as well as HBV-DNA>1 000(HR:1.204,95%CI:[0.920,2.540],P=0.038)were adverse factors for prognosis.ConclusionLiver resection is better than TACE for BCLC-C patients with portal vein tumor thrombosis.However,randomized controlled trial still need to be used to further confirm our conclusion.

ABSTRACT

[ Abstract] Objective To investigate the effect of IL-8 on the viability and migration of HepG2 cells and the potential effect of integrins (αsubunits ) on the migration of HepG2 cells.Methods HepG2 cells were stimulated by IL-8 at different concentrations ranging from 0 to 125 ng/ml in vitro.MTT assay was preformed to detect the viability of HepG2 cells.Scratch wound migration assay was used to explore the effect of IL-8 on the migration of HepG2 cells at the time points of 0, 4, 8, 12 and 24 h,respectively.Transwell assay was conducted to detect the vertical migration of HepG2 cells after stimulation with IL-8 for 24 h.The F-actin of HepG2 cells was observed by immunofluorescence analysis after treatment with IL-8 at different concentrations.The expression of αsubunits of integrins in HepG2 cells treated with IL-8 for 8h was detected using Western boltting assays.Results Compared with the control group, HepG2 cells treated with IL-8 showed improved proliferation activities, but there was no significant difference between the groups of HepG2 cells treated with IL-8 at different concentrations.The cell scratch healing assays and Transwell analysis both indicated that IL-8 promoted the migration of HepG2 cells in a dose-dependent manner.Meanwhile, the cytoskeleton of HepG2 cells was rearranged and the number of filopodium-like protrusions (FLPs) was increased rapidly after treatment with IL-8.Western blotting analysis showed that IL-8 up-regulated the expression of αsubunit of integrins and there was a concentration difference betweenαsubunits.Conclusion IL-8 promotes the migration of HepG2 cells by up-regulating the expression ofαsubunits, and different αsubunits may play different roles.

ABSTRACT

Objective To explore the clinical pathologic characteristics of gallbladder cancer and prognostic factors for patients with gallbladder cancer.Methods We retrospectively reviewed 108 patients diagnosed pathologically with gallbladder cancer and treated in HuBei Three Gorges Polytechnic Medical College,Yichang Central People's Hospital and Yichang First People's Hospital from January 2003 to December 2012.Kaplan-Meier method was used to estimate survival.The association between the clinicopathologic characteristic and the prognosis in gallbladder cancer patients was assessed using Log-rank test.Cox proportional hazards model was used to determine independent risk factors.Results All patients were followed up from 3 to 102 months,the median follow-up time was 46 months.There were 77 deaths (71.3%),31 patients are alive.Survival time after operation was from 4-98 months.The mean and the median survival time were 28.4 months and 17 months respectively.The 1,2,3 and 5-year overall survival rates were 54.2%,37.5%,31.3% and 21.6%.Multivariate analysis indicated independent risk factors were such as incidental gallbladder cancer,lymph node metastasis,poor differentiation.Conclusions Gallbladder cancer is a malignancy with poor prognosis.Incidental gallbladder cancer,lymph node metastasis,tumor poor differentiation are independent risk factors.

ABSTRACT

Objective To investigate the etiology of iatrogenic bile duct injury and experience in its diagnosis and treatment. Methods A retrospective study was conducted on the clinical data of 86 patients with iatrogenic trauma in the bile duct. Results These 86 cases have received a total of 156 sessions of surgical procedures, including 2 explorations in 66 cases,3 explorations in 6 cases. Lateral bile duct injury in 22 cases was treated by suture repair and T tube stent. Eight cases suffering from iatrogenic transection of the common bile duct were retrieved by cholangiojejunostomy and T tube stent. Nine cases with inadvertent CBD ligature were managed by a lysis and T tube stent. Roux en Y cholangiojejunostomy was adopted in 77 cases. Sixty cases were followed up for 1~10 years, with good result in 90% of the cases. Conclusions Most CBD iatrogenic injury cases were encountered as a result of cholecystectomy.Roux en Y cholangiojejunostomy is the choice of therapy.
